In 2013, some rather poor pictures of an unusual Hypancistrus from Jacareacanga, Rio Tapajos system, Brazil, were shared online. Through conversations with my friend Heriberto Gimenes Junior, a Brazilian ichthyologist, the location (Ramal, Jacareacanga) was verified. In 2021 this small species was given the number L518 by Ingo Seidel, who managed to get hold of a small group despite a very high price tag. Most individuals were (and still are) sent to markets in Asia where there is a stronger will to pay big money for them. So far this interesting species, which is among the smallest of the genus, has not become widely available in the hobby.
Facts:
Name: Hypancistrus sp.
Trade names: Hypancistrus sp. “Jacareacanga”, L518
Origin: Jacareacanga, Rio Tapajos, Brazil
Maximum size: 8 cm / 3”
As with all Hypancistrus, this species needs an aquarium set up consisting of lots of hiding places in the form of rocks, wood and of course specially made caves that suit their measurements. In these the males will eventually guard their offspring. They prefer water that is fairly warm (27-30 C), soft and slightly acidic. Most of all it should be well oxygenated and clean, so a good filtration system and frequent water changes are essential. It’s a rather small and timid species that should not be exposed to too much competition over food and shelter. Among themselves they are peaceful, although males may quarrel for caves and females can sometimes be badly injured or even killed during the breeding-trapping in the male’s cave.
